RPS28 is a structural component of the small ribosomal subunit (40S) that plays a critical role in protein synthesis and ribosome biogenesis 123. During ribosomal assembly, RPS28 incorporates into the small subunit processome where it associates with nascent pre-rRNA and ribosome biogenesis factors to facilitate RNA folding, modifications, and processing 4. RPS28 translation is post-transcriptionally regulated by tRNA-derived small RNAs; inhibition of LeuCAG3'tsRNA reduces RPS28 mRNA translation, impairing pre-18S rRNA processing and reducing 40S subunit production 5. RPS28 mutations cause Diamond-Blackfan anemia (DBA) with mandibulofacial dysostosis, a ribosomopathy characterized by erythroid aplasia, physical anomalies, and cancer predisposition 67. De novo mutations affecting the RPS28 start codon represent a novel pathogenic mechanism in DBA 7. Beyond developmental disease, RPS28 expression is elevated in cancer contexts: fibrillarin-dependent rRNA methylation modulates RPS28 incorporation to support oncogenic translation in triple-negative breast cancer 8, while ribosome biogenesis-related genes including RPS28 drive clear cell renal carcinoma progression and predict poor prognosis 9. These findings establish RPS28 as both a fundamental ribosomal component and a disease-relevant gene linking ribosome biogenesis to development, hematologic disorders, and cancer.
